Note: Lead is listed as (Pb) in the periodic table of elements.

In the information below, Pb will refer to Lead solder, and PbF will refer to Lead Free Solder.

The Lead Free Solder used in our manufacturing process and discussed below is Sn(Tin)+Ag(Silver)

+ Cu(Copper).

This model uses Pb Free solder in it's manufacture due to environmental conservation issues.

PCBs manufactured using lead free solder will have the PbF within a leaf Symbol

front of PCB.

Caution

• Pb free solder has a higher melting point than standard solder. Typically the melting

point is 30 ~ 40 °C higher. Please use a high temperature soldering iron

and set it to 350 ± 5°C.

• Pb free solder will tend to splash when heated too high (about 1100 °F or 600 °C).

If you must use Pb solder, please completely remove all of the Pb free solder on the

pins or solder area before applying Pb solder. If this is not practical, be sure to heat the

Pb free solder until it melts, before applying Pb solder.

• After applying PbF solder to double layered boards, please check the component side

for excess solder which may flow onto the opposite side. (see figure below)

Suggested Pb free solder

There are several kinds of Pb free solder available for purchase. Although, this product can be

used only Sn+Ag+Cu(tin, silver, copper) solder
